Original application filed September 27, 1901, Serial No. 76,746.Divided and this application iiled April 23, 1908. Serial No. 153,904.

To cir/ZZ wto'm, t may concern:

Beit known that I, ARTHUR H.WooDwARD, a citizenot' the United States,residing at Chicago.v in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Bell Mechanism forRegisters, of which the following is a specitication.

My invention relates to bell mechanisms for registers, and has for itsobject to provide a new and improved mechanism ot' this description.

My present application is a division ot' my prior application, tiledSeptember 27, 1901, Serial No. 76,746.

My invention is illustrated in the accompanying drawings, wherein# sFigure 1 is a view of aregister embodying my invention with theface-plate removed. Fig. 2 is a sect-ion on line 2 2, Fig. l. Fig. 3 isa view of bell-operating mechanism. Fig. 4 is a view of the safety-doglocated between the two bell-operating mechanisms. Fig. 5 is a side viewof said dog apart from the mechanism. Fig. 6 is a view of Fig. 5 as seenfrom below. 7 is a view ot the bell-operating mechanism, showing theparts when the bell-hammer has been released. Fig. 8 is a view similarto Fig. 7 just prior to the release of the bell-liammer.

Like letters refer to like parts throughout the several figures.

I have illustrated my invention in connection with fare-registersadapted to registerv two classes of fares. rThe register mechanismproper is contained within the case A,

' provided with a suitable cover and adapted to be connected to aremovable back. I/Vithin the case A are provided the two trip-registersand the two permanent registers. Two operating-levers F and G arepivotally connected to the register-case and ai'e provided withprojecting pins or parts Y, which project beyond the register-case andwhich are actuated by the mechanism associated with the removable back.These operating-levers are connected with the mechanism of the register,so as to operate such mechanism when moved. As illustrated in thedrawings, the

tripregister B and the permanent register D and associated partsform onemechanism tor registering one kind of fares and the trip-reg-A ister Cand permanent register E and associated parts t'orm another mechanismfor regof the mechanism associated with the back ot c the registereither of these register mechanisms can be operated from any given pointin the car.

As indicated in the drawings, the two tripregisters are arranged toindicate cash fares and transfers, although ot course it is evident thatthey could indicate any other kind ot' `fares desired. I provide twodifferent bells having ditferenttonesone adapted to be rung when oneclass oi' fares is registered and the other adapted to be rung when theother class of fares is registered. In the construction illustrated inthe drawings I place these bells outside of the register-case proper,providing an exterior chamber inclosed by the exterior bell-casing` O,attached to the main registercase by screws, which are inserted from theinside, so that they cannot be tampered with except by taking ott thetop of the registercase.

The bells P and Q, as herein shown, are mounted one within the other toeconomize space, the inner bell Q being loosely mounted upon thesupportR. The bell-hammers P/ and Q are located in the bell-casing andare provided with the hammer-arms P2 and Q2, which are contained withinthe casing and which may be integral with the bell-liammers or connectedthereto in any other desired manner. These hammers are connected to theposts P3 and Q3 and may be integral with said posts or attached theretoin any desired manner. Mounted concentric with the hammer-arms are thehammer-levers P1L and Q", provided with notched ends, as shown in Figs.l and 3. These hammer-levers are connected by the connecting-rods P5 andQ5 to the operatinglevers F and G, as shown in Fig. 1. Pivotallyconnected with the hammer-levers are the hammer -dogs P and QG.` Thesedogs have a limited movement about their pivotal connection with thehammer levers, such movement being' obtained by the pins PT and Q7,attached to the hammer-levers, working in enlarged holes in thehammer-dogs. (See Fig.

Located between the two hammer-levers is a safety-dog S,adaptcd tocooperate with both of said levers and to engage the notches Sl in theface of the levers, so as to prevent them from beingl moved back beforeringing the bell IOO after they have been started in motion. This safety-dog is illustrated in detail in Figs. 4, 5, and 6 and is pivotallyconnected to the base of the register-case and the holding-piece S2. Thedog works about its center as a pivot and is connected to acontrolling-spring S3 by means of a link S1. This spring besidescontrolling this dog has other functions and aids in the control of thehammer-dogs P6 Q15. lt will be noted that in this mechanism for ringingthe two bells the mechanism is arranged so that a partial stroke ofeither is im possible, and yet there is used only three springs, thesafety-dog springs S3 and the two bell-hammer springs Si.

Each of the hammer-dogs P2 Q11 has a series of working faces adapted toperform a separate function. The faces P2 Q8 engage the hammer-arms, soas to lift the hammers when the hammer-levers are moved. The inclinedfaces P'J Q1 engage the stationary parts or posts P10 Q10, so as to movethe hammer-dogs to release the hammer-arms. The faces P11 Q11 engage thesafety-dog and release it simultaneously with the release of thehammer-that is, simultaneously with the disengagement of the faces PS QSwith the hammerarms P2 Q2. The faces P12 Q12 engage the stationary partsP12 Q11 when the dogs are moved back to their initial position and movesaid dogs from their released to their operative position-that is, theposition where they engage the hammer-arms P2 Q2. Said dogs also havethe projections or faces P11 Q11, which are engaged by the safety-dog asthe hammer-dogs are moved forward, so as to insure the engagement of thehammer-dogs with the hammer-arms and prevent them from missing thehammer-arms due to jarring or the like during the first part of theirforward movement. It will thus be seen that these hammer-dogs have noseparate springs of their own, and yet perform a series of functionsnecessitating their being' held in different relative positions atdifferent times.

It will be seen that in this construction there is a bell-hammer and ahammer-lever for operating the bell-hammer oscillating around the samecenter and a hammer-dog carried by the hammer-lever adapted to lift thebellhammer and release it at the end of the stroke, the release being apositive release at a predetermined point. There is also asafety-dogfreely engaging the notched end of the hammer-lever when it is beingmoved forward, but which positively7 engages said level' if it isattempted to move it backward at any point between its initial and finalpositions. This safety-dog to be effective is released simultaneouslywith the ringing of the bell. This feature is necessary to thesatisfactory operation of the device, for if the safety-dog is releasedan instant too soon the parts may be moved to their initial positionwithout ringrelease of the safety-dog and the operator ceases moving thelever the mechanism does not return to its initial position. If, forexample, it is desired to registera transfer fare, the operating-lever Gis moved. The motion of the operating-lever G is communicated to thehammer-lever by the rod Q1, and said hammer-lever is moved forward. Thehammer-dog Q, being attached to said lever, is moved forward andreleased from the post Q13. The projection or face Q1'1 is then engagedby the safety-dog S, so as to insure the engagement of the face Qs withthe hammerarm Q2. The hammer-arm is then moved so as to move thebell-hammer away from the bell. As the parts approach the end of thestroke the beveled face Q" engages the stop Q10 and the hammer-dogismoved so as to release the arm Q2. The spring S2 then returns thebell-hammer and rings the bell. Simultaneously with this release and theringing of the bell occurs the release of the safetydog. The parts areshown just prior to the release of the hammer-arm in Fig. 8. In Fig. 7the parts are shown after the hammer-arm has been released and beforethe parts are returned to their initial position. When the bell has beenrung, the handle is released by the operator and the spring in the backof the register moves the parts to their initial position.
